Abstract

This invention provides an adhesive composition for the negative electrode of a non-aqueous secondary battery. This adhesive composition exhibits excellent elastic deformation characteristics and film-forming properties in response to volume changes of the active material, and also demonstrates excellent durability (electrolyte resistance) to electrolytes, enabling the formation of a secondary battery with excellent charge-discharge efficiency and capacity retention. The adhesive composition for the negative electrode of a non-aqueous secondary battery contains core-shell particles (A) having a shell composed of polymer (a1) and a core composed of polymer (a2), and an aqueous medium (B). Polymer (a1) contains structural units derived from a reactive emulsifier, structural units derived from a vinyl monomer with acidic groups, and structural units derived from a (meth)acrylate monomer. Polymer (a2) contains structural units derived from a conjugated diene monomer and structural units derived from an aromatic vinyl monomer. none
